Abstract
Official abstract text for this publication.
An electrophotographic photosensitive member that includes the outermost surface layer formed by curing a mixture of a charge transporting substance having a chain-polymerizable functional group and a urea compound represented by the following formula (1) or (2), and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrophotographic photosensitive member, comprising: a conductive support, a photosensitive layer provided on the support, wherein the electrophotographic photosensitive member comprises a surface layer comprising a polymer obtained by the polymerization of a composition comprising: a charge transporting substance with at least one chain-polymerizable functional group, and a urea compound, wherein the urea compound is at least one compound se…
